The first musical instrument was probably made by the first person because
humans are essentially musical and use music in lots of different ways. The
first musical instrument might have been their voice, or they might have
used objects around them. They might also have used their body as a musical
instrument during movement or dance by clapping or stamping.

There are lots of natural objects like wood, stone, shell, and bone, that
can make a ringing sound (resonate) when struck or blown. These instruments might be decorated
or made into a different shape or size. Some instruments date from the time
that humans developed the skills to make them. The first metal instruments,
for example, would date from the iron and bronze ages, in the same way that
electronic instruments date from the twentieth century.

No one really knows who made the first musical instrument, or what it was,
because we don't have any written accounts or recordings, and nobody who is
alive now was there at the time to tell us the answer. Even if we look at
archaeological remains, it is difficult to identify all the objects that
might have been used during music making. But whatever the first instrument
was, it would have carried special meaning for the person who made, used or
listened to it.
